The Federal Aviation Administration, citing fire hazards, has warned against using Samsung Galaxy Note 7 smartphones on aircraft. 美国联邦航空管理局(Federal Aviation Administration)以火灾危险性为由警告不要在飞机上用于三星盖乐世Note 7(Samsung Galaxy Note 7)智能手机。Three Australian airlines and the German carrier Lufthansa have outright banned their use onboard.三家澳大利亚航空公司和德国汉莎航空公司(Lufthansa)则具体禁令在机上用于该产品。But the threat of airliner fires is not limited to Samsung devices, which the company has offered to replace. 不过，飞机上的火灾威胁不仅仅限于三星的电子设备（三星已明确提出对调）。

And the hazard is far more than theoretical.这些危险性也不仅是理论上的。Qantas, one of the Australian carriers, had an onboard fire during a trans-Pacific flight this year when a passenger’s cellphone was crushed in the mechanism of a business-class seat and the phone’s lithium-ion battery ignited.今年，澳洲航空公司(Qantas)的飞机在一次横跨太平洋飞行中再次发生火灾，一名乘客的手机被商务舱座位的机械装置碎裂，锂离子电池发生爆炸。In January as a Delta Air Lines flight from Minneapolis to Atlanta arrived at the gate, crew members discovered that a carry-on bag containing two laptop computers had burst into flames, according to the FAA The smoke prompted some passengers to use the emergency exits and wait on the wings until help arrived.今年1月，美国联邦航空管理局报告，一架从明尼阿波利斯飞抵亚特兰大的达美航空公司(Delta Air Lines)客机到达登机口时，机组成员找到一件装有两台笔记本电脑的随身行李发生爆炸。

烟雾被迫一些乘客用于应急出口离开了，在机翼上等候，以后救援人员抵达。The problem is lithium-ion batteries, which have become the standard for portable consumer electronics, including phones, tablets and laptops, because of the power they can pack into a small package. 问题出有在锂离子电池身上，它已沦为便携式电子产品的标配，还包括手机、平板电脑和手提电脑，因为一块小小的锂离子电池能存储大量电能。

They are also highly volatile.但它们也十分不平稳。Battery fires were considered a contributing factor in the crashes of three cargo planes in the last 10 years: an Asiana 747 in 2011, a UPS 747 in Dubai in 2010 and a UPS DC-8 in Philadelphia in 2006.电池发生爆炸被指出是过去10年中三架货运飞机失事的一个诱因：2011年韩亚航空公司(Asiana)的747飞机；2010年UPS的747飞机（在迪拜），以及2006年UPS的DC-8飞机（在费城）。

In January, the FAA issued a warning that lithium-ion batteries in a cargo hold carried the risk of a catastrophic hull loss on an airplane.今年1月，美国联邦航空管理局公布警告，货舱中的锂离子电池对飞机具备灾难性壳体损失风险。So far there have been no airliner disasters specifically attributed to passengers’ digital devices. 到目前为止，还没具体因乘客的数码设备而导致的空难。But experts worry about the sheer mathematics. 但非常简单统计资料一下数字，就不足以让专家担忧。The Royal Aeronautical Society in Britain estimates that even a single-aisle jet with only 100 passengers might have more than 500 lithium-ion batteries aboard. 英国皇家航空协会(Royal Aeronautical Society in Britain)估算，就连一架仅有能配备100名乘客的单通道飞机也有可能装有500多块锂离子电池。

Those numbers, and the attendant fire risks, could eventually catch up with the air-traveling public.那些电池以及预示的火灾风险有可能最后损害搭乘飞机旅行的公众。The question is: What to do about it — besides issuing advisories?问题：除了公布警告之外，我们还能怎么办？The FAA administrator, Michael P. 美国联邦航空管理局局长迈克尔P胡尔塔(Michael P. Huerta, said in an email statement that the agency recognized that the batteries posed risks and that it was tracking all incidents in aircraft cabins to help us determine what we can do. Huerta)在电子邮件声明中称之为，该机构认识到电池具备风险，正在研究所有机舱事故，协助我们确认能做到些什么。

Huerta urged passengers to put their devices in a carry-on bag or other safe location when not using them.胡尔塔强烈建议乘客把不必的电子设备放进随身行李或其他安全性的地方。But the FAA is in a tough situation. 不过，美国联邦航空管理局正处于艰苦的境地。Under the regulatory rules, it cannot ground the Galaxy Note 7 until the Consumer Product Safety Commission orders a recall. 按照管理规定，它无法禁令盖乐世Note 7上飞机，除非消费产品安全委员会(Consumer Product Safety Commission)命令解任。

On Friday, the safety commission said it was working with Samsung on the terms of a recall and urged owners of the phones to stop using them. 周五，该安全性委员会称之为，正在与三星协商解任事宜，并呼吁那些手机的所有者不要用于它们。On Saturday, Samsung offered new guidance to owners: Turn off your phone and bring it in for a replacement.周六，三星给顾客们获取了新的方案：开动手机，当作替换。Congress has limited the FAA’s ability to place restrictions on battery-powered devices on airplanes beyond the recommendations of the International Civil Aviation Organization, according to Laura Brown, an FAA spokeswoman. 据美国联邦航空管理局的发言人劳拉布朗(Laura Brown)称之为，国会容许美国联邦航空管理局在国际民用航空的组织(International Civil Aviation Organization)的建议之外，对机上电池供电设备展开更加多容许。

The organization, a U.N. agency, says the devices should not be transported on passenger planes as cargo or in checked baggage. 后者是联合国的辖下机构，它回应，这些设备不应当在客机上作为货物运输，也不该在托运行李中运输。As for in-cabin use, the organization defers to each country’s rules.至于在机舱内的用于，该的组织留下每个国家自行规定。

Any attempt to seriously restrict or even ban devices powered by lithium-ion batteries would probably face an outcry from travelers, who have come to consider them an indispensable part of modern life. 旅客们早已把手机视作现代生活不可缺少的一部分，任何严苛容许甚至禁令这些以锂离子电池设备的尝试都有可能招来强烈抗议。There would also be the question of who would enforce such rules, and how. 另外，还有谁来继续执行以及如何继续执行这些规定的问题。Airport security check-in processes are already long and tedious, without adding a new layer of scrutiny.机场安全检查托运过程早已很漫长无趣，更加别提再行特一层审查。

Until a few years ago, before the in-cabin use of phones and other electronic devices was allowed below 10,000 feet, it was widely known that passengers surreptitiously defied the rule. 几年前，在1万英尺以下的机舱内用于手机等电子设备仍然被禁令。在那之前，众所周知，乘客往往偷偷地自行其是。

Flight attendants complained that it was impossible to police.乘务员责怪说道，他们无法管束。So the goal is to contain the hazard. 所以，目标是掌控危险性。

In the event of a lithium-ion battery fire in flight, FAA standards may help minimize the damage.当飞行中遇上锂离子电池起火的情况时，美国联邦航空管理局的标准或许可以协助把损失减少到大于。Seat covers, carpets, curtains and dividers are made of special materials that are flame retardant, even against a lithium-ion battery fire, which burns in the neighborhood of 1,000 degrees Fahrenheit, according to Isidor Buchmann, an engineer who runs the informational site BatteryUniversity.com.座套、地毯、窗帘和拆分帘由类似的防水材料制成，甚至能抵御锂离子电池引起的火情。

据信息网站BatteryUniversity.com的运营工程师伊西多布克曼(Isidor Buchmann)称之为，这种材料在周围温度超过1000华氏度（约合538摄氏度）时会自燃。Some experts say those standards could suffice.有些专家称之为，这些标准早已充足。It’s damned near impossible to propagate a fire on an airplane, said George J. Ringger, an aeronautical engineer with his own consulting company who specializes in cabin interiors. 在飞机上，火势完全不有可能蔓延到，航空工程师乔治J林格(George J. Ringger)说道。

他自己的咨询公司专门获取机舱内部设施方面的建议。Could a passenger get burned? Yes. 乘客否有可能被灼伤？有可能。Would there be smoke that would propagate in the cabin? Do crews have protocols? Yes.烟雾否有可能在机舱蔓延到？机组成员否有应急方案？是的。

But some other fire and safety experts are not as sanguine. 但是其他一些火灾和安全性专家不这么悲观。A laptop battery fire could take hours to burn itself out. 如果手提电脑的电池发生爆炸，有可能要在数小时后才能火。And the smoke emitted would be abundant and toxic.有可能获释大量剧毒烟雾。Michael Gilchrist is an engineer and co-owner of PlaneGard, a maker of a case meant to contain the fire and smoke if a battery starts to malfunction. 工程师迈克尔吉尔克里斯特(Michael Gilchrist)是PlaneGard公司的牵头所有者。

该公司生产一种箱子，电池功能紊乱时放进去，可以容许火和烟雾蔓延到。Customers include Air Tahiti Nui, which carries the PlaneGard case on transoceanic flights.它的客户还包括塔希提航空公司(Air Tahiti Nui)，后者在横跨大洋的航班上配有了PlaneGard盒。With a full-blown laptop, you see what happens, Gilchrist said. You have a 35- or 40-minute event. 对于一台原始的笔记本电脑，情况不会是这样，吉尔克里斯特说道，那不会是一场持续35至40分钟的事故。

That could cause a lot of problems.不会造成很多问题。
